Display flickering and tinted green
As of yesterday I am having some issues with the display of my Galaxy S9. My screen is super washed out and dark and tinted yellow/green. It sometimes goes back to normal, but will randomly give issues again as I use it.
I did have a spill a couple of weeks ago, after which I immediately powered the phone off and cleaned all of the ports with electrical contact cleaner. Then I let the phone dry out for around 3 days. It was working fine after that until yesterday.
- Screen is washed out / yellowed, not very bright, sometimes flickering.
- Using the brightness slider makes the screen even worse.
- When powering the phone off, it shows the Galaxy S9 logo with a normal screen, and midway displaying the “Samsung” logo, it turns terrible again.
- The screen looks normal in screen recordings and in screen mirroring, so I don’t believe this to be a graphics issue.
What I’ve tried:
- Leaving the phone off for a few days in dessicant.
- Restarting the phone in safe mode, didn’t seem to help.
- Uninstalling recently installed apps, didn’t help.
In the past 2-3 weeks, there has been a number of reports about a similar screen issue with the S9. This is leading me to believe it may be something related to firmware or software updates, rather than related to my spill.
My phone is getting quite old as I purchased it on release. I was looking into replacing the battery and fingerprint sensor anyways, as they are both quite used. I figured I might as well get everything done at once.
I found this video on YouTube which shows what I believe to be the same issue - https://youtu.be/k8ybjAjardI - in which the solution is to replace the display flex connector of the screen, rather than the entirety of the display.
Can somebody explain to me where to get that part, and how exactly to replace it? The video is quite confusing, but the part is supposedly quite cheap compared to the screen. I’m not exactly sure what’s going on in the video.
Thanks for any tips and help.
